Cold War espionage

Cold War espionage describes the intelligence gathering activities during the Cold War between the Western allies and the Eastern Bloc. Both relied on a wide variety of military and civilian agencies in this pursuit.

Corona (satellite) Series of American strategic reconnaissance satellites (1959-72)

The CORONA program was a series of American strategic reconnaissance satellites produced and operated by the Central Intelligence Agency (CIA) Directorate of Science & Technology with substantial assistance from the U.S. Air Force. The CORONA satellites were used for photographic surveillance of the Soviet Union (USSR), China, and other areas beginning in June 1959 and ending in May 1972.

Astronomical object Large natural physical entity in space

In astronomy, an astronomical object or celestial object is a naturally occurring physical entity, association, or structure that exists in the observable universe. In astronomy, the terms object and body are often used interchangeably. However, an astronomical body or celestial body is a single, tightly bound, contiguous entity, while an astronomical or celestial object is a complex, less cohesively bound structure, which may consist of multiple bodies or even other objects with substructures.

KH-7 Gambit

BYEMAN codenamed GAMBIT, the KH-7 was a reconnaissance satellite used by the United States from July 1963 to June 1967. Like the older CORONA system, it acquired imagery intelligence by taking photographs and returning the undeveloped film to earth. It achieved a typical ground-resolution of 2 ft (0.61 m) to 3 ft (0.91 m). Though most of the imagery from the KH-7 satellites was declassified in 2002, details of the satellite program remained classified until 2011.

KH-8 Gambit 3

The KH-8 was a long-lived series of reconnaissance satellites of the "Key Hole" (KH) series used by the United States from July 1966 to April 1984, and also known as Low Altitude Surveillance Platform. The satellite ejected "film-bucket" canisters of photographic film that were retrieved as they descended through the atmosphere by parachute. Ground resolution of the mature satellite system was better than 4 inches (0.10 m). There were 54 launch attempts of the 3,000 kilogram satellites, all from Vandenberg Air Force Base, on variants of the Titan III rocket. Three launches failed to achieve orbit. The first one was satellite #5 on April 26, 1967 which fell into the Pacific Ocean after the Titan second stage developed low thrust. The second was satellite #35 on May 20, 1972 which suffered an Agena pneumatic regulator failure and reentered the atmosphere. A few months later, pieces of the satellite turned up in England and the US managed to arrange for their hasty return. The third failure was satellite #39 on June 26, 1973 which suffered a stuck Agena fuel valve. The Bell 8096 engine failed to start and the satellite burned up in the atmosphere. The KH-8 was manufactured by Lockheed. The camera system/satellite was manufactured by Eastman Kodak's A&O Division in Rochester, New York.

KH-11 Kennen Type of American spy satellite

The KH-11 KENNEN is a type of reconnaissance satellite first launched by the American National Reconnaissance Office in December 1976. Manufactured by Lockheed in Sunnyvale, California, the KH-11 was the first American spy satellite to use electro-optical digital imaging, and so offer real-time optical observations.

Enhanced Imaging System (EIS), officially referred to as "Enhanced Imagery System", previously known as 8X, and sometimes unofficially known as Misty 2 and KH-13, is an American reconnaissance satellite program. A derivative of the Improved Crystal satellites, EIS replaced Misty, and was intended to provide more coverage and dwell time than previous reconnaissance satellites; like Misty, it has stealth capabilities. Only one EIS satellite has been launched; USA-144, which was placed into orbit by a Titan IVB rocket on 22 May 1999.

A sphere is a three-dimensional object shaped like a ball; it may also refer to a sphere-like region or shell.

Carina Nebula H II region in the constellation Carina

The Carina Nebula or Eta Carinae Nebula is a large, complex area of bright and dark nebulosity in the constellation Carina, and is located in the Carina–Sagittarius Arm. The nebula is approximately 8,500 light-years (2,600 pc) from Earth.

Ararat anomaly

The Ararat anomaly is an object appearing on photographs of the snowfields near the summit of Mount Ararat, Turkey, and advanced by some Christian believers as the remains of Noah's Ark.

Buttonhole

Buttonholes are reinforced holes in fabric that buttons pass through, allowing one piece of fabric to be secured to another. The raw edges of a buttonhole are usually finished with stitching. This may be done either by hand or by a sewing machine. Some forms of button, such as a frog, use a loop of cloth or rope instead of a buttonhole. Buttonholes can also refer to flowers worn in the lapel buttonhole of a coat or jacket, which are referred to simply as "buttonholes" or boutonnières.

Key Hole (KH) is the designation for a series of American optical reconnaissance satellites:

KH-9 Hexagon American family of spy satellites

KH-9, commonly known as Big Bird or KeyHole-9, was a series of photographic reconnaissance satellites launched by the United States between 1971 and 1986. Of twenty launch attempts by the National Reconnaissance Office, all but one were successful. Photographic film aboard the KH-9 was sent back to Earth in recoverable film return capsules for processing and interpretation. The best ground resolution achieved by the main cameras was better than 0.6 metres.

Thorad-Agena

The Thorad-Agena was an American expendable launch system, derived from the Thor and Delta rockets. The first stage of the rocket was a stretched Thor variant named "Long Tank Thrust Augmented Thor". The Long Tank Thor first stage was later adopted by NASA's Delta program for its "Thrust Augmented Improved Delta", which first flew in 1968. The second stage was the Agena-D, which had already been used in conjunction with the standard configuration Thor, as the Thor-Agena. Three Castor rockets would be used as boosters. Most launches carried Corona (KeyHole) reconnaissance satellites, particularly spacecraft of the KH-4 series, however some scientific and technology development satellites were also flown, mostly towards the end of the program.

KH-13 is an unofficial designation which may refer to several US reconnaissance satellite programmes; a continuation of the Key Hole series which officially ended at KH-11:

Discoverer 4 Reconnaissance satellite

Discoverer 4, also known as Corona 9001, was an American optical reconnaissance satellite launched on 25 Jun 1959 at 22:47:45 GMT, the first of ten operational flights of the Corona KH-1 spy satellite series, and the first satellite to be equipped for photo surveillance. The satellite was not successfully orbited.

Discoverer 9 Reconnaissance satellite

Discoverer 9, also known as Corona 9006, was an American optical reconnaissance satellite launched on 4 Feb 1960 at 18:51:45 GMT, the sixth of ten operational flights of the Corona KH-1 spy satellite series, and the first of them to be equipped with a new, vacuum-proof, polyester-based film. The satellite was not successfully orbited.

Discoverer 12 Reconnaissance satellite

Discoverer 12 was an American optical reconnaissance satellite launched on 29 Jun 1960 at 22:00:44 GMT. The fourth of five test flights of the Corona KH-1 spy satellite series, it was lost when the second stage failed during launch.
